BLOWPIPE.

SPECIFICATION forming part of Letters Patent No. 773,203, dated October 25, 1904. Application filed August 31, 1903. Serial No. 171,350. (No model.)

To all 1071,0717, it may concern:

Be it known that I, EUGENE H. FOSDICK, a citizen of the United States. residing a Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Blowpipe, of which the following is a specification.

This invention relates to blowpipes; and one object of the invention is to provide a blowpipe by which flames of various sizes are almost instantaneously obtained by a simple adjustment of the device.

Another object is to provide a blowpipe which may be readily adjusted to direct the flame as desired.

Other objects of the invention are to produce a device of the character described which is extremely simple in construction, elfective in operation, and may be easily controlled.

Herctofore it has been usual to employ independent burners for each size of flame desired. Sometimes detachable nozzles of different sizes are provided with a burner, so as to have at command the desired size of flame. The first is objectionable because of the inconvenience of having several burners on the bench, which takes up room, and the second is objectionable because to change the size of the flame necessitates turning out the lire, removing the outer gas-nozzle sleeve, taking off the air-jet, and replacing by the one desired to give a suitable flame. The outer gas-nozzle sleeve has then to be replaced and the lire ignited.

In the present invention the burner is equal in capacity to several burners, but is compact in form and may be readily manipulated, there being three blowpipes on one base.

The invention has manifold applications in general laboratory work, such as ignitions, for brazing, and for glass-blowing.

The accompanying drawings illustrate the invention, and referring to the same, Figure I is a side elevation of the blowpipe. Fig.

II is a plan view of the blowpipe. Fig. III is a front elevation of the blowpipe. Fig. IV is a rear elevation of the blowpipe. Fig.

VIII is a view of the rear face of the segmental nozzle-carrier. Fig. IX is a face view of the segmental supporting-plate. Fig. X is a View looking at the bottom wall of a nozzle.

Briefly, the present embodiment of the invention comprises a nozzle-carrier equipped with nozzles of various sizes, the nozzle-carrier being movable to bring a desired nozzle into communication with a supply-feeder.

The invention further comprises means whereby the nozzle-carrier may be adjusted so as todirect the flame from a nozzle in the desired direction.

1 designates a base from which a standard 2 projects.

3 is a segmental feeder-plate, the lower end of which is provided with a knuckle 4:, ar-

ranged transversely thereof and which is held in close contact with a similar knuckle 5, carried by the standard 2, by means of a screw 6, which passes through both knuckles. The screw 6 may be provided with a finger-lever 7 for operating the same and loosening or tightening the screw to clam p the two knuckles together, so that the feeder-plate may be adjusted to the proper pitch or inclination relatively to the base 1.

A segmental nozzle-carrier 8 is swiveled on a bolt 9, which is mounted in the feeder-plate 3, there being a washer 10, which lies next to the feeder-plate, and a coil-spring 11. interposed between the washer and the nut on the bolt 9. The nozzle-carrier 8 lies flatly against the feeder-plate 3, and the contacting faces of the feeder-plate 3 and nozzlecarrier 8 are perfectly smooth. The strength of the spring 11 is sufiicient to hold the contacting faces tightly enough together to prevent any escape of gas or air, although the spring will allow the nozzle-carrier to be shifted on the feeder-plate 3.

The feeder-plate 3 is provided with an airpassage 12 and a gas-passage 13, there being an air-cock l4: screwed to the passage 12 and a gas-cock 15 screwed into the passage 13.

A pilot-light is maintained from a jet-pipe 16, which projects from a cock 17, which is connected by pipe 18 with the gas-cock 15.

In the present embodiment I have shown the nozzle-carrier as constructed to support three lmrner-nozzles, (designated 19, 20, and

21, respectively.) These nozzles may be of any desired form; but in my preferred construction each burner-nozzle comprises an outer shell 22, which is tapered at one end to lit snugly within a taper hole in the nozzlecarrier. Within the shell 22 is an air-tube 23, preferably of glass to reduce friction, which is supported concentric: lly within the shell at the rear by a bushing 24:, which may preferably be of soft rubber, so as to form a tight non-leakahle joint. The fm'ward part of the air-tube 23 may be supported by means of conteringscrews The centering-screws 25 may preferably be arranged equidistant in the shell 22 and are of a size suflieientlysmall to not impede the passage of gas to an appreciable extent. The airtube terminates short of the end of the shell 22, which thereby forms a combined mixing-tn be and burner-nozzle of the usual construction. The shell 22 near its inner end on its lower side is provided with an orilice 26, which registers with an air-passage in the nozzle-carrier.

Referring to Fig. Vlll, it will be seen that in the present embodiment the nozzle-carrier is provided with three gas-passages 2T, 28, and 29, respectively. T hose gas-passages are formed radially, as shown, and have horizontal galleries 30, b1, and 32, respectively. Either of the gas-passages is adapted to be brought into communication with the gas-passage 13 in the feeder-plate 3. The nozzle-carrier 8 is provided with a handle 33, by which it may be moved to bring either of the nozzles into communication with the gas and air passages 13 and 12 in the feeder-plate The nozzlecarrier 8 may be yieldingly locked in position when a nozzle is in register with the passages 12 and 13 by means of aspring locking-plate 34, which has a slight projection 35, adapted to engage in depressions 36, 3. and 38, sunk in the upper rim of the m zzlecarrier 8.

if a small needle-flame is desired, the operator throws the nozzle-carrier over to bring the nozzle it) to the center of the feeder-plate 3, the plate locking and positioning it auton'iatieally. hen the nozzle-carrier is in this position, the gas-passage 27 is in communication with the gas-passage l3 and the airtube 2?; of the nozzle 19 is in communication with theair-passage 12. The cocks Hand are adjusted to admit the requisite respective amounts of ai and gas to the nozzle, according to the judgment of the operator. If the next larger flame is desired, the operator moves the nozzle-carrier into the position shown in Fig. ll. to bring the middle nozzle 20 into communication with the air and gas passa es 12 and 13, while if the largest flame is desired the operator moves the nozzle-carrier to bring the nozzle 21 into communication with the air and gas passages 12 and 13. The pilot-light 16 may be kept alight constantly, so that in working the burner the operator has at his immediate command a flame of the desired size and quality, either flame being obtained instantly by throwing the nozzle-carrier into the requisite position, the pilot-light 16 instantly igniting the gas which issues from the centered nozzle as soon as the nozzle is in register with the air and gas passages.

The valuable feature of having at instant command a flame of the desired size is supplemented by the adjustability of the burner to direct the flame to the particular angle desired. The adjustment of direction of flame is made very quickly by loosening the screw 6 by means of the handle 7, tilting the feederplate, nozzle-carrier, and attached. parts to the desired angle as one piece, and then clamping the screw 6 by a slight turn of the lever.

\Vhile 1. have shown and described the preferred embodiment of my burner, in which the nozzle-carrier is constructed to carry three nozzles, I do not limit myself to the number of nozzles supported by the carrier, for the nozzle-carrier could be constructed to support a less number than three, and it could also be constructed to carry more nozzles than three Neither do 1 li mit myself to the particular shape of the nozzle-carrier, feeder-plate, or other parts,asitisevidentthattheconstructionofthe same could be varied without departing from the spirit of my invention. Neither do I limit myself to mounting the nozzle pivotal] y or arranging the nozzles at points concentric with the pivot. Furthermore, a blowpipe embodying in its construction a plurality of nozzles, means for supporting the same, a feeding means combined therewith, one of the two latter elements being movable relatively to the other for producing a discharge of the combustion matter through the desired nozzle, would lie within the scope of my invention. Neither do 1 limit i'nyself to the precise construction for adjusting the flame to the angle desired, as any means for adjusting the nozzle relative to the base may be employed.
